Does anyone know of an opinion permitting Matzah to be cooked in a skillet(instead of being baked in an oven), and if so under what circumstances?
Shulchan Aruch 461:2 refers to an "ilfas," which is a kind of wide pan used for baking. The SA rules that it needs to be pre-heated before use. Actually, the Menachos in the Beis Hamikdash, which had to be matzah, were baked in pans. So it is definitely possible. But whether it is allowed l'maaseh is an entirely different story.
